Danu

Danu is the most ancient of the Irish gods by the tradition’s own reckoning — not a figure who acts within the myths so much as the source from which every other Irish deity’s collective name descends. The Tuatha Dé Danann are, quite literally, “the people of the goddess Danu,” and her position as their common mother makes her less a character in any single story than the ground from which all the stories’ characters are said to spring.

The most ancient divinity

Charles Squire’s synthesis of Gaelic mythology states her precedence directly: “The most ancient divinity of whom we have any knowledge is Danu herself, the goddess from whom the whole hierarchy of gods received its name of Tuatha Dé Danann.” Where figures like Balor, Bress, and Elathan among the Fomor “show clearest to us” as individual personalities, Squire notes that even their own ancestry fades into “shadows following into oblivion” the further back the tradition is traced — and Danu stands at the point where that tracing stops, the oldest name the surviving material still preserves.

Anu, Ana, and the Paps

Danu’s alternate names carry their own testimony to her age and reach: “she was also called Anu or Ana, and her name still clings to two well-known mountains near Killarney,” a pair of hills known in Irish tradition as the Dá Chich Anann — the Paps of Ana — a landscape feature literally shaped, in local naming, like the breasts of the mother-goddess who nursed the divine race. A ninth-century Irish glossary commentator is quoted for the tradition’s own summary of her role: “well she used to cherish the gods” — cherishing, not ruling, being the quality the tradition remembers her by.

Mother of the earth’s fruitfulness

Squire draws the comparison directly to the Greek Demeter, proposing that “Danu herself probably represented the earth and its fruitfulness.” Whether or not every later god of the Tuatha Dé Danann is literally her offspring in a genealogical sense, Squire notes that “all the other gods are, at least by title, her children” — including Nuada Argetlám, the Silver-Handed, whom Squire identifies as the tradition’s Zeus-figure and its war-god, greatest among the divine children the name Tuatha Dé Danann collectively claims for Danu.

Danu and the Tuatha Dé Danann

Gregory’s narrative retelling introduces the divine race more simply, as “the people of the gods of Dana, or as some called them, the Men of Dea,” arriving in Ireland “through the air and the high air” — a brief notice that assumes, rather than explains, the goddess behind the name. Read alongside Squire’s fuller account, the two sources together preserve what the corpus can honestly attest: Danu is remembered less through episodes of her own than through the entire pantheon that carries her name forward, and through a landscape — the Paps of Ana — that still bears her form in the hills themselves.
